4x^2 + 5x - 8 + (- 4x^2 - 5x + 8) = 0

all ur doing is changing the signs so they will cancel each other out.

so ur adding : -4x^2 - 5x + 8

Answer:

v= -2

Step-by-step explanation:

10+2v=−6(3v+5)

Step 1: Simplify both sides of the equation.

10+2v=−6(3v+5)10+2v=(−6)(3v)+(−6)(5)(Distribute)10+2v=−18v+−302v+10=−18v−30Step 2:

Add 18v to both sides.

2v+10+18v=−18v−30+18v20v+10=−30

Step 3:

Subtract 10 from both sides

.20v+10−10=−30−1020v=−40

Step 4:

Divide both sides by 20.20v20=−4020v=−2

Answer:v=−2
